INSECT-POWDER BLOWER.

Specification of Letters Patent No. 25,526, dated September 20, 1859.

To all whom "it may concern:

Be it known that we, PETER REYNARD, of the city of New York, and VICTOR VARIN, of Brooklyn, in the county of Kings, State of New York, have invented, made, and applied to use a certain new and useful Improvement in Insect-Powder Blowers; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing, making part of this specification, wherein Figure 1 is a longitudinal section of said blower as in use, and Fig. 2 is a cross section thereof at the line 1, 1.

Similar letters denote the same parts.

For the destruction of roaches, insects and vermin of different kinds it is usual to use a powder, and the more said powder is blown into the cracks and crevices the better. For this purpose bellows with a hopper have been used. The powder has also been placed in an india rubber ball with a nozzle. These devices are either costly or unhandy in use.

Our said invention consists in a receptacle containing the powder constructed with divisions, whereby the powder is sustained in such a manner that the air blown through agitates and carries away with it the said powder; and to give the wind to blowing apparatus we insert an india rubber ball having a hole in it in such a manner as to form a cheap durable and efiicient bellows.

In the drawing a, is a cylinder of sheet metal having a tapering end or neck and a movable pipe or nozzle Z) c, c, are cross plates or divisions inserted in the cylinder and neck as seen in Fig. 2, and d, is a perforated diaphragm soldered into the cylinder.

hen the nozzle 5, is removed and powder inserted it remains between the divisions c, 0, and on the perforated diaphragm (Z, consequently when wind is blown by competent means through the cylinder at, it is sure to carry with it a'porti0n ofthe powder because it cannot all settle to one side of the cylinder when said cylinder is in either an inclined or horizontal position, but resting on these divisions as seen in Fig. 2, is blown with force into the crevices and to a distance often otherwise inaccessible.

e, is an india rubber ball inserted into the open rear end of the cylinder a, having a hole therein as at f and being attached by cement against the ring 9. By pressing on this ball with the thumb or fingers the air will be expelled as to cause the necessary blast through the powder chamber.

Having thus described our said invention what we claim as new and desire to secure by Letters Patent is The divisions c, 0, in the powder chamber to insure the powder being in a position to be acted on by the air blown through the perforated diaphragm (Z, as and for the purposes set forth, and in combination with said powder chamber constructed as aforesaid we claim the india rubber perforated ball fitted and acting as specified to give the blast of air.

In witness we have hereunto set our signatures this second day of September, 1859.
